Recommendations for the rational application of lubricants for the main components of machine tools

Due to the wide variety of metal cutting machine tools, the structure and components have changed a lot, it is difficult to give a clear opinion on the selection of lubricants for its main components. The following content is recommended for the rational application of lubricants for some of the main components of machine tools according to relevant standards. Comments for reference when selecting lubricants.

1. Recommended lubricants for machine tools:

Full loss system: exquisite mineral oil, L-AN32, L-AN68 or L-AN220, for light duty components, often using HL hydraulic oil.

2, gear (closed gear): continuous lubrication (splash, circulation or jet), refined mineral oil, and improve its antioxidant, corrosion resistance (ferrous and non-ferrous metals) and anti-foaming, CKB32, CKB68 or CKB100 , CKB150, closed gears with light load and small operation (related to headstock bearings, cutter boxes, carriages, etc.), CKB32 and CKB68 can also be used for mechanical control of clutch overflow lubrication, CKB68 can replace AN68. HL hydraulic oil is used in the box; refined mineral oil, and its anti-oxidation, corrosion resistance (black and non-ferrous metals), anti-foaming, extreme pressure and anti-wear properties, CKC100, CKC150, CKC200, CKC320, CKC460, Any type of closed gear (except hypoid gears) and associated bearings that operate at normal or medium constant temperatures and under heavy loads can also be used for manual and centralized lubrication of lead screws, feed screws and light duty rails.

3, spindle, bearing and clutch: spindle, bearing and clutch, refined mineral oil, additives to improve its resistance and corrosion and oxygen resistance, FC2, FC5, FC10, FC22, sliding bearings or rolling bearings and related clutch pressure, oil Bath and oil mist lubrication, in the case of a clutch system, due to the risk of corrosion, it is required to use products without anti-wear and extreme pressure agents; spindles, bearings, refined mineral oil, and additives to improve their corrosion resistance , anti-oxidation and anti-wear properties, FD2, FD5, FD10, FD22, sliding bearing or rolling bearing pressure, oil bath and oil mist lubrication, can also be used for components requiring oil viscosity, such as precision machinery, hydraulic or hydraulic Lubrication of pneumatic machinery, solenoid valves, oil lubricators and hydrostatic bearings.

4. Guide rail: exquisite mineral oil, and improve its lubricity and stick-slip property, G68, G100, G150, G220, used for lubrication of sliding bearings and guide rails, especially suitable for low-speed motion rail lubrication, so that the guide rails are “crawling” "The phenomenon is reduced to a minimum, and it can also be used for lubrication of various sliding parts such as screw, feed screw, cam, ratchet and light duty worm gear for intermittent operation.

5, hydraulic system: hydraulic system, refined mineral oil, and improve its anti-rust, anti-oxidation and anti-foaming, HL32, HL46, HL68; refined mineral oil, and improve its anti-rust, anti-oxidation, anti-wear and anti-foam , HM15, HM32, HM46, HM68, general hydraulic system including heavy-duty components, also suitable for lubrication of sliding bearings, rolling bearings and all kinds of normal loads and gears (except worm gears and hypoid gears), HM32 and HM68 Replacing CKB32 and CKB68 respectively; exquisite mineral oil, and improving its anti-rust, anti-oxidation, viscosity temperature and anti-foaming properties, HV22, HV32, HV46, CNC machine tools, in some cases, HV oil can replace HM oil. Hydraulic and rail system, refined mineral oil, and improved rust, oxygen, anti-wear, anti-foam and stick-slip, HG32, HG68, used in sliding bearings, hydraulic rail lubrication systems to reduce the rail at low speed The "crawling" phenomenon of the lower movement, if the viscosity of the oil is suitable, can also be used for a separate rail system, HG68 can replace G68.

5, the use of grease: general grease, and improve its resistance to oxygen and corrosion, XBA or XEB1, XEB2, XEB3, ordinary rolling bearings, open gear and various parts requiring fatliquoring.
